Current SPST Switch

The H934 is a microprocessor based current monitoring device that are designed to provide unique solutions by accurately monitoring the status of motors controlled by variable frequency drives preventing the motors from damage.

Overview

The H934 is a microprocessor based current monitoring device that are designed to provide unique solutions by accurately monitoring the status of motors controlled by variable frequency drives preventing the motors from damage.

The current sensor stores the sensed ampere values for normal operation at various frequency ranges in non-volatile memory and this stored data is used to distinguish between a reduced amp draw due to normal changes in the frequency and an abnormal amp drop due to belt loss or other mechanical failures. The relay on the H934 is isolated from the current switch, and all relay connections are externally accessible on the device. The features such as nuisance reduction, rapid troubleshooting make the sensor efficient and reliable.
